Formulae on Transport In Plants


Value of wall pressure of a cell equals the value of its turgor pressure, so is also the parity between the values of its pressure potential and matrix potential

Auxin application reduces pressure potential (and matrix potential) and thus increases the water potential of a cell.

The highest value of water potential (and also that of osmotic potential) is zero, which is that of pure water. Water potential (and osmotic potential) of a living protoplasm/cell is always lower than zero (like for example-3 atmosphere or-4 atmosphere).
Water Potential = Osmotic Potential + Pressure Potential.
